by the pivot pins 5, 5 of said'link. Said member tca'rries the member 6which is formed integral therewith and which extends at right ang estherefrom away from said, chainl, is of appreciable length and has itsends curved back. Said member 6 at its edge away from member 4 carriesthe spacer member 7 which is fixed thereto as by riveting, bolting, or sot welding. Fixed to the otherfa'ce of mem er 7 and extending to acorresponding member 7 on chain ,1'-'. (see Fig. 4) is the T-shapedIload support flight 9 which cooperates with a corresponding flight 10in supporting a load :11, suchasa tray, pan or the like.

In Fig. 4 the set of-chainsl, 1? which carry chains 12, 12' which carrythe set of flights 10 and are caused'to travel together upwardly ordownwardly in manner well known in this art by means of the sprocketwheels 14, 14

,and 15, .15. which are mounted on the shafts 16 and 17 respectively anddriven by. a suitable source of power notshown. 1

The angle members 20, 20 and 22,22 extend about two sides-of therespective chain portions 1,-1','12 and 12' with one of the side membersthereof positioned between the backs of the flights 9, 10 and themembers 6, 6 which are on that part of the chains, the members 7 '7serving to space the flights and members 6, 6' apart to provide slotwhich rides over said side member of the an 1e. angle .forms a guardabout t e vertically ex- The whole tending part of the chainwh'ich ridesthrough,

and preferably the angle is provided to extend throughout thevertical'part of the chains between top and bottom sprockets, beingproperly mounted by means not shown to the frame work of the conveyer.Between the angles 20 and 20' there extends the sheet. iron partition 25which is formed at desired points about the space through which themembers 4 and6 move and close to and along the backs of the flights 9, 9where serves as a guard wall for trays, pans, etc., on said flight andfor food, dishes, or other goods on said trays, etc. Alike partitionmember 25' extendsbetween angles 22 and 22. The space between a moved upor down in pairs by their respective chains 1 and 1', and 12 and 12' inamannerwell known in the art, said flights are made to'carry loads suchas the tray or pan llwhich ex tends between a cooperating pair offlights. Such a load tends to cause the flights and their pairs ofchains to bend away from each other,

but the back of the flights and the members 6, 6 which with respectivemembers 7 7f form angles which ride against a side'memberiof arespective angle member 20 'andpreventexcessive movement of members ofloaded pairs of flights away fromeach other. The angle members alsoserve -as protective shields about the'chains and also as supports forthe partition or closure membersiwhich extend Jetween theuil] Theguiding maging; mounted Ioutside the ends of the fli hts asabovedescribed, is particularly useful in jconveyersj comprising a chainwhich passes over sprocketfwh'eels with a carrying elementsuch as aflight hereoi on i the inside of the chain, as does anger the chains inthe conveyer shown; 11 my said Patent No. 1,504,886. The adv ntage liesin that the guiding meansdoesnot interfere with the carrying elementwhenthe'lattcr is on the inside of the chain and the form of the latterdoes not have to be'modified in order to avoid interference between thecarrying element-and the sprocket, such as heretoforewas I necessary. vg

While I have shown and described and have pointed out in the. annexed=claiins certain novel features of the invention, it will be-understoodthat various omissions, substitutions and changes in the formsanddetails of the device illustrated and in its operation and use may bemade by thoseskilled in the art without departing from the spirit of thein vention. y I a Having thus described my invention what I claim anddesire to secure by Letters Patentis 1. In a conveying mechanismcomprising a pair of flexible transmission members 'and' a spanningmember therebetweou adapted to move a load, in combination, connectingmembers between each of said transmission members and said spanningmember including one which for a part of its length'extends over saidspanning member and defines therewith a guide channel.

2.
